The resource management firm has signed a 10-year contract to deliver secure, low carbon energy supplies.

The 4MW CHP units replace older models and are expected to help the university reduce carbon emissions across its campus by 35% before 2020, compared to 1990 levels.

Annual carbon emissions are predicted to fall by 4,000 tonnes across the 320-acre site.

The energy produced by the system will be transported through the university’s district heating and cooling network to academic and research buildings.

In addition to the CHP units, energy efficient boilers and pumps, a number of 200,000-litre thermal stores have been installed to capture excess heat for later use.

Richard Bettle, Energy and Utilities Manager at the UEA, said: “These latest CHP engines replaced the original engines installed in 1999 and along with a third existing CHP engine, will allow us to generate over 80% of electricity on site, reducing costs and carbon dioxide emissions.”
